The IxTP experience of iFe is akin to hysteria. For INTPs, paranoia can be a not uncommon manifestation.In its extreme form, the grip experience of Introverted Thinking types may manifest as a feeling of profound and infinite separateness from the whole of humanity.
They fear that once in the realm of intense emotion, they may become possessed by it and never be able to get out. That is why descending into “the depths” is rare and entered into against the will of the Introverted Thinking type.
With greater intensity, inferior Feeling comes out as raw, extreme emotion.
Feeling judgment seems to become increasingly exaggerated and obsessive, reaching a point where it no longer serves a judging purpose but becomes unbridled emotionalism.
I think you're right. I have always maintained that Ts are more broken than Fs.which isn't to say that I won't be easily convinced to the contrary, but the dynamic on this thread suggests that my hypothesis is correct, in addition to @Kalach's posts about Te-dominance being what led to the creation of this thread in the first place.
But, if you think about it, it's logical that primitive and raw feeling would be scarier / more disorienting than primitive and raw thinking. Not least because we are all equipped to experience emotion, whether we want to or not, but we are not all equipped to understand the inadequacies of our own thinking... Experiencing a rigid (though delusional) certainty is not necessarily distressing for the feeler (however frustrating it may be for the people who have to deal with the consequences of that individual's faulty thinking). Experiencing an extreme and primitive emotional outburst (your own or someone else's) is always distressing for a thinker.
